Mozilla is testing a new "Smart Window" in Firefox, a separate, optional window that lets users chat with an AI assistant while browsing. The company has opened a waitlist for early testers at firefox.com/ai, signaling a cautious move into AI integration. The feature is designed to sit alongside Classic and Private modes, giving users full control over when and how to use AI.
Smart Window is explicitly opt-in, with Mozilla emphasizing that users will never be locked into one ecosystem or have AI forced into their experience. This stance builds on features already present in Firefox, such as the sidebar chatbot on desktop and Shake to Summarize on iOS. Mozilla also introduced a one-click AI kill switch earlier this year, which ties into the Project Nova redesign.
The browser AI landscape has become a privacy battleground, with companies taking divergent approaches. Brave launched its LEO assistant as a privacy-first alternative, while Perplexity Comet, Microsoft Edge, and Opera Neon have embraced AI-centric designs. OpenAI reportedly killed its Atlas browser to focus on a broader app, and Google experimented with silently downloading a local AI model in Chrome.
Mozilla frames Smart Window as a response to browsers built by AI companies, which it argues force a binary choice between constant AI use or none at all. The company's announcement stresses that users should decide independently, positioning Firefox as the independent option. This perspective aligns with its broader mission of keeping AI "open, accessible, and driven by choice."
The waitlist is currently open, and the feature will remain off unless a user actively enables it. Mozilla says it is building in the open and seeks feedback from first testers to refine the experience. The future of Smart Window will likely depend on user adoption and the competitive pressure from AI-first rivals.
